My invention relates to protecting means for rolls of paper, and it has among its salient objects to provide a cheap and efficient cap which can be applied to the end of a roll of paper and secured thereto for the purpose of protecting the roll against damage, either from indentation or tearing or from water, said protecting means being made waterproof.

It is known that in handling and shipping large and heavy rolls of paper s ch as are used in newspaper publication, that the rolls are frequently damaged by being watersoaked at the end, or by reason of-indentation or tearing the margin of the paper is so damaged that it is necessary to recut the roll and thus great waste and loss is entailed.

I have conceived the idea of making a special paper cap which can be applied to the ends of a roll of paper in a pliable condition and clamped in place for a time to allow the same to set and become hard, after which the clamping means can be removed and the pro tecting means is thus secured in place and becomes sufficiently hard and stiff as to form a most efiicient protection for the end of the roll, as well as to protect it from being water soaked.

I accomplish this by building up a body of several layers of paper, secured together by means of a special matter which not only adheres the layers together, but is capable of hardening in an unusual manner and render ing the composite structure verystiff and hard, much as starchhardens the bosom of a shirt or a collar.

In order to explain my invention 1 have illustrated one practical embodiment thereof on the accompanying sheet of drawings, which I will now describe.

Figure 1 is a side elevation of the end of a roll of paper, showing the wrapper or outside sheet torn away and indicating in light broken lines a protecting cap in place;

Figure 2 is an enlarged edge elevation of five layers of paper as formed and prepared for application to the end of the roll;

Figure 3 is a side elevation of one form of, clamping means for pressing and temporarily holding the structure over the endof the roll l of paper; Figure which are laid together to form the cap, each successive sheet being torn away to expose a portion of each sheet or disc and to show the portion covered by the adhesive used;

. Figure 5 is an end View of the clamping means shown in Fig. 3; r

I igure 6 is an elevation of the roll of paper with the finished protecting means applied thereto; and

Figure 7 is an end view thereof. Referring more in detail to the drawings, a roll of paper is designated 10,.With a cover or wrapper sheet 11, torn back in Fig. 1, and with an end plug 12, which projects slightly from the end of the roll andwhich also serves to make the roll easily tilted for the purpose of pushing the lifting lip of a lifting truck under the end of the roll when it is desired to .move it. r

In Figs. 2 and 4, I have shown five sheets or discs of heavy-paper placed together fiatwise and have designated these in Fig. 4, as 13, 14, 15, 16 and 17 I apply a wide ring of special adhesive to each layer as it is applied for securing them together and to the top layer 17, is applieda similar or narrower ring of adhesive for causing the top disc or layer to adhere to the wrapper sheet 11,

' around the outsidev of the'roll as said composite structure is pressed over the end-of the the cap in place around the end of. the roll,

as will be readily understood.- These layers are applied while in their soft and pliable condition and'are easily pressed'over the end of the roll, and arethen clamped and held tight by the clamping means, as described and as will beclear fromthe showing. 1i After 4 is a fiat view of the discs of paper the composite structure of the cap or protecting means has had time to set and to harden, the clamping means is removed, and the roll is ready for shipment and appears as seen in Fig. 6, with the balancing plug 12, bulging out sufiiciently to serve its purpose and make it easy for the heavy roll to be tilted for the purpose described. The finished 'cap is designated 13, inasmuch as the bottomv layer in Fig. 4, would become the outside layer in the applied cap.

I will now describe the special adhesive or stiffening and water-proofing matter I use I in building up the composite structure forming the finished cap or protecting means. As I have actually used this preparation it is composed of the following ingredients: glue 23% plaster, of Paris 11% cement 2% para-tlin 5% marble dust 2% and Water 57%.

This is prepared by mixing the glue and water and stirring the other ingredients thereinto with. the result that it takes a gelatin form or consistency and when used as the adhesive for securing the layers of the paper together, it not only securely holds said layers together, but as it sets and hardens it forms said structure into a very hard protecting means for the roll of paper and is I bodiment thereof,

adhered to the outside wrapper of the roll and is thus easily removed when said outside wrapper is cut or torn intermediate the ends of the roll and removed therefrom. It also forms a water-proof structure for protecting the ends of said rolls.

I do not, of course, limit my invention to any particular or specific details herein described in order to set forth one practical emrealizing that many changes in said details can be made Within the scope of my invention and I intend that I' shall only be limited by the hereto appended claims.

I claim: g 1

l. A protecting wrapping for a roll of paper which includes a wrapper sheet around the roll of paper, a protecting cap formed of p a plurality of superimposed layers secured together with an adhesive adapted to harden, with means for crimping the outer edge of said composite cap-forming layers overthe end of said roll of paper and securing them around the end of said wrapper sheet and holding said formed cap until hard, said cap being removable with said Wrapper sheet.

2. A protecting wrapplng-for a roll of paper having an end plug in each end -pro Jectmg shgntly beyond the end of said roll of paper, said protecting Wrapping including a wrapper sheet around the roll of paper as 1 a. separate wrapper, a protecting cap formed of a plurality'oii' superimposed layers secured together flatwise by means of adhesive adapted to harden and applied in rings around the outer edges of said layers, whereby the central part of said layers'is free of. adhesive in its inner side over the end of said plug, and means for crimping the outer edge of said composite cap-forming layers over the EDWARD L.
